The WT & Awake are available on CDs in mp3 format.
The society produces a library CD annually which contains a lot of their literature & magazines.
It is interesting to watch this publishing company try to transform. They are scratching, clawing, kicking, and screaming as they are torn from their antiquated business model. Not as many people are reading print, especially the garbage the WTS puts out -- their own "publishers" don't even read the magazines. It is cheaper for them to produce CDs rather than print.
The WTS will still need to print their rules & regs to keep the publishers in line. I suppose they will probably print one internal publication for the publishers, a combination KM/Sunday study article. And there will be one magazine for non-JW/public consumption.
